DRIVING MECHANISM.

Application filed July 13, 1915.

To all whom 'it may concern.:

Be it known that I, HERMAN Kxisnn, a citizen ot' the United States, residing` at East Oaklandin the county ot Alameda and State ot' California. have invented certain new and uselul lnprovenlents in Driving Mechanism; and l do hereby declare the. following to be a iull. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

'lhis invention relates to driving mechanism t'or motor trucks and cars; and it consists in the novel construction and combination of the )arts hereinafter fully described and claimed.

In the drawings. Figure 1 is a front view of the driving mechanism as constructed according to this invention. Fig. 2 is a crosssection, taken on the line 2 2 in Fig. l.

As the driving mechanisms are alike at both sides of the motor ti'uck the description and illustration will be confined to one of them. The trame or body 2l ot the truck is provided with a spring l, a leatl spring being preferably used. A bearing or block 5 is secured to this spring, and (i is a tubular axle which is secured in the bearing 5, and which does not revolve. This axle has a shoulder or collar 7 which. prevents it from moving endwise. A b a1-ing o is secured in the end portion of the tubular axle, and is preferably a roller bearing or other antifrietion bearing.

A driving shaft S) is journaled in the bearing S, and is provided with a driving wheel 10 which is preferably a portion otl a compensating gear of approved construction. A sleeve l2 is mounted on the end portion of the tubulaiaxle, and has a plate or disk 14 on its outer end. pivoted at its upper end to the. car :trame 3 by a pin 1G, and it has an eye 17 which is keyed on the inner end portion of the sleeve 12, which abuts against the rshoulder 'l'.

A road wheel 2O of any approved make is journaled concentric with the sleeve 12, and 21 are antifriction rollers or other similar devices interposed between the hub of the wheel and the sleeve.

An internal toothed wheel 24 is formed on' or secured to one side of the road wheel, and forms a gear casing 25 which is provided with a :removable cover 26. A toothed Specification. of Letters Patent.

A radius link 15 is Patented Jail. 4. 1916.

serial No. 39,635. i

pinion 2T is secured on the end portion of 55 the revoluble sha lt il inside the gear casing, and 2o are idle toothed wheels journaled on pins 29 which project laterally from the plate or disk 14. The wheels 28 gear into the pinion 2T and into the internal wheel 60 and they transmit the motion of the I snait to the road wheels.

The power ot the roadwheels on the road is transmitted to the. truck or car frame by the radius link which is` inclined upwardly and forwardlv olthe axle, and which permits the. truck or car frame to move vertically on its supporting spring or springs, and these springs have no st ain on them due to the propelling action. rl`he radius 7o link also forms a convenient support for the brake mechanism which is of an Y approved construction, and which operates on the brake-*drum or wheel 3() which projects from the inner side portion of the ground wheel. i

The radius link holds the two pinions or idle wheels substantially on the vertical center line ot the `ground wheel, in which position they are found to drive to the best advantage, and it permits the sleeve to oscillate to a slight extent on the tubular axle to adapt itself to the movements of the supporting spring. The arrangement of the pinions on opposite sides ot' the center of S5 the ground wheel also distributes the strain on the bearings and less driving power is consequently required.

ll'hat claim is:

l. In a driving mechanism, a car frame, 9G a 1i iii-i'e,t'ollll)le tubular axle, a spring interposed between the said axle and frame, a drivingshaft journaled concentric with the axle. a radius link pivoted at one end to the car trame and operatively connected with the tubular axle, a road wheel journaled concentric with the axle. an internal toothed wheel secured to the road wheel, a toothed pinion secured on the driving shaft, and idle. toothed wheels operatively connected with the radius link and gearing into the said internal wheels and the said pinion.

2. In a driving mechanism, a car frame, a non-revoluble tubular axle. a spring interposed betwcen the said axle and frame, a driving shaft journalcd concentric with the axle, a sleeve mounted to oscillate on the tubular axle and having a plate on its outer sleeve, a road Wheel journaled concentric 5` with the axle and sleeve, an internal toothed 'j wheelI secured to the road Wheel, a toothed pinionseeured on -the driving shaft, and

idle toothedwheels supported bythe said plate and gearing into the said internal wheel and the said pinion'.

In testimony whereof I signature.
